Yes, Instube can fetch videos from YouTube when you paste the video URL, but downloading copyrighted material may violate YouTube's terms of service.

No, Instube works on standard Android devices without requiring root privileges.

This usually means the APK is incompatible with your Android version, the file is corrupted, or installation from unknown sources is disabled.

Instube is designed for recent Android releases; however, compatibility is not officially confirmed, so you may need to test it on Android 15.

Updating the app normally does not delete existing media files, but it’s a good practice to back up important downloads before updating.

Instube does not impose a strict size limit, but very large files may be constrained by your device’s storage space and network stability.
